The episode picks up directly from last week, as scientists begin testing Wendy’s connection to the alien species. After being knocked unconscious by the painful frequencies of the xenomorphs, Arthur and the team temporarily take her hearing offline for study. When it is restored, Wendy explains that she followed the sounds to the lab and realized she was hearing a baby xenomorph scream from Kirsch’s experiments. Though the scientists propose disconnecting her from the signals, Wendy insists the aliens have chosen her, while Boy Kavalier wants to exploit her ability to decode their language. Wendy’s powers soon expand—she reproduces the alien frequencies so others can hear them as well. Despite warnings about the danger of the aliens realizing the team can listen, Boy Kavalier refuses to return the specimens to Yutani.
Wendy reconnects with Hermit in one of the show’s most heartfelt sequences, showing him her room and sharing a tender moment watching Ice Age. Hermit reassures her that his anger is directed at Prodigy for tearing their family apart, not at her. Their bond deepens, though Slightly grows jealous of Hermit’s presence, further fracturing the Lost Boys’ fragile dynamic.
Meanwhile, Morrow continues to manipulate Slightly, coercing him into stealing a xenomorph egg by threatening his mother and brothers. Though Slightly resists, Morrow escalates his plan, plotting to use him to smuggle a facehugger victim back under his control.
Elsewhere, Kirsch begins testing another alien specimen—an eyeball-like creature with tentacles. In a disturbing sequence, it removes a sheep’s eye, implants itself, and seizes control of the animal’s body, demonstrating its intelligence and terrifying potential. At the same time, Sylvia and Arthur discuss the risks ahead, but their conversation is interrupted when Nibs reveals she is pregnant. Later, Sylvia presses her about the claim and pivots to questions about her alien encounter during the rescue mission. Nibs reacts with an aggressive outburst, forcing Sylvia to de-escalate and call security. The event is formally classified as a “level 3 incident,” highlighting just how unstable Nibs has become.
The episode’s climax brings Wendy back into the lab, where she witnesses the alien growing inside Hermit’s surgically removed lung. When the creature bursts free, Wendy communicates directly with the newborn xenomorph and even reaches out to pet it—cementing a chilling but profound connection between her and the species. Kirsch watches in awe, recognizing her growing, almost unearthly capabilities.
The fourth episode of Alien: Earth is a gripping blend of sci-fi horror and human drama, grounding its high-concept ideas in deeply personal stakes. Morrow’s manipulation of Slightly adds layers of tension, while Wendy’s evolution as the lead is both unsettling and captivating.
The performances continue to elevate the material. Babou Ceesay is menacing as Morrow, the Weylan-Yutani cyborg obsessed with recovering the alien cargo, and his presence injects constant unease. Sydney Chandler, meanwhile, carries the series with a delicate balance of childlike innocence and eerie connection to the xenomorphs, making Wendy one of the most fascinating protagonists in the Alien franchise.
With standout direction, layered character work, and escalating stakes, Alien: Earth continues to surpass expectations week after week, cementing itself as must-see television.
